Went there with my two children, got within about a half-mile before being foiled by the combination of steep hills, immature thistles, and a four-year-old's patience. Saw two other geohashers on the way in, and another five on the way out. Hope some of 'em made it!

Drove nearby with Claire, discovered that 152 near the spot is actually a highway instead of the two-lane country road I remembered it being. Then had to drive five miles down the highway to find a suitable place to turn around, whoops (I missed at least one perfectly good turn around at the Dinosaur Point road). On the way back, we stopped a few time to get proof of our lack-of-access, and then waited at the Bell Station Cafe's closed and locked gate for about twenty minutes before heading back.

Parked nearby in a dirt field, ran across the exit and then entrance ramps, wandered around the dried-out weeds for a while until I got to the exact point (within 7 feet, at the limit of the GPS's accuracy, anyway). Got pictures for proof, and headed out. Land Geohash achieved! Headed back at 4pm with the kids and met quite a large group. Note: Bring Pete's food next time.

Got to the parking lot fairly late in the evening -- 6:45, with sundown (and gates locked) at 8:23. Tore up the trail, hiking fast enough to pass a pair of mountain bikers who were also going up. After about forty minutes I got to the Powder House, where I encountered several deer (including a four-fuzzy-point juvenile buck) who weren't particularly happy to see me. Headed down the upper part of the April Trail loop until the GPS told me I was near, then tromped off-trail into thick poison oak. The GPS claimed I needed to go straight up a hillside, and kept telling me that I was perpetually just northwest of the spot all the way until I managed to climb the entire hill off-trail and get back to the Mine Trail above. At that point, I pulled out the second GPS and discovered that tree coverage was such that the GPSes were telling me to go in opposite directions. So I re-pocketed the smaller one, let the bigger one settle down, and slid back down the hill to the approximate location to take proof pictures. After that it was a quick jog back to the car, arriving at 8:15. Eight minutes to spare.
